Thread: Valve chatter only under heavy load..

Hey guys, i just installed some jwt cams on my car. I started her up and she runs gr8, no werid sounds, i rev it to 7k almost, no sounds....but as soon as i put it in gear and accelerate i get a light to moderate valve chattering sound...=/ Can someone point me in the right direction to what i should do?

Is everything torqued to correct specs? Also, are you sure it is not detonation?
